Eyewear controlling an uav

ABSTRACT

Eyewear configured to control an unmanned aerial vehicle (UAV). In one example, a user interacts with the eyewear to generate control signals that are transmitted to the UAV to control the flight path, speed, orientation, and to communicate other instructions to the UAV. An input of the eyewear is controlled by the user to control the UAV, such as a touchpad, a microphone, a head movement tracker and a camera. The user is also able to configure and customize the eyewear to send specific control signals to the UAV as a function of user actions. This includes specific head movements and head gestures of the user as a method of controlling the UAV. This allows the user to control the UAV in a more natural and convenient way.

DETAILED DESCRIPTION

Examples described herein include eyewear configured to control an unmanned aerial vehicle (UAV). In one example, a user interacts with the eyewear to generate control signals that are transmitted to the UAV to control the flight path, speed, orientation, and to communicate other instructions to the UAV. An input of the eyewear is controlled by the user to control the UAV, such as a touchpad, a head movement tracker, a microphone, and a camera. The user is also able to configure and customize the eyewear to send specific control signals to the UAV as a function of user actions. This includes specific head movements and head gestures of the user as a method of controlling the UAV. This allows the user to control the UAV in a more natural and convenient way.

Additional objects, advantages and novel features of the examples will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following and the accompanying drawings or may be learned by production or operation of the examples. The objects and advantages of the present subject matter may be realized and attained by means of the methodologies, instrumentalities and combinations particularly pointed out in the appended claims.

In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well known methods, procedures, components, and circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings.

The term “coupled” as used herein refers to any logical, optical, physical or electrical connection, link or the like by which signals or light produced or supplied by one system element are imparted to another coupled element. Unless described otherwise, coupled elements or devices are not necessarily directly connected to one another and may be separated by intermediate components, elements or communication media that may modify, manipulate or carry the light or signals.

The orientations of the eyewear device, associated components and any complete devices incorporating an eye scanner and camera such as shown in any of the drawings, are given by way of example only, for illustration and discussion purposes. In operation for a particular variable optical processing application, the eyewear device may be oriented in any other direction suitable to the particular application of the eyewear device, for example up, down, sideways, or any other orientation. Also, to the extent used herein, any directional term, such as front, rear, inwards, outwards, towards, left, right, lateral, longitudinal, up, down, upper, lower, top, bottom and side, are used by way of example only, and are not limiting as to direction or orientation of any optic or component of an optic constructed as otherwise described herein.

Reference now is made in detail to the examples illustrated in the accompanying drawings and discussed below.

FIG. 1A is a side view of an example hardware configuration of an eyewear device 100, which includes a right optical assembly 180B with an image display 180D (FIG. 2A). Eyewear device 100 includes multiple visible light cameras 114A-B (FIG. 7 ) that form a stereo camera, of which the right visible light camera 114B is located on a right temple 110B.

The left and right visible light cameras 114A-B have an image sensor that is sensitive to the visible light range wavelength. Each of the visible light cameras 114A-B have a different frontward facing angle of coverage, for example, visible light camera 114B has the depicted angle of coverage 111B. The angle of coverage is an angle range which the image sensor of the visible light camera 114A-B picks up electromagnetic radiation and generates images. Examples of such visible lights camera 114A-B include a high-resolution complementary metal-oxide-semiconductor (CMOS) image sensor and a video graphic array (VGA) camera, such as 640p (e.g., 640×480 pixels for a total of 0.3 megapixels), 720p, or 1080p. Image sensor data from the visible light cameras 114A-B are captured along with geolocation data, digitized by an image processor, and stored in a memory.

To provide stereoscopic vision, visible light cameras 114A-B may be coupled to an image processor (element 912 of FIG. 9 ) for digital processing along with a timestamp in which the image of the scene is captured. Image processor 912 includes circuitry to receive signals from the visible light camera 114A-B and process those signals from the visible light cameras 114A-B into a format suitable for storage in the memory (element 934 of FIG. 9 ). The timestamp can be added by the image processor 912 or other processor, which controls operation of the visible light cameras 114A-B. Visible light cameras 114A-B allow the stereo camera to simulate human binocular vision. Stereo cameras provide the ability to reproduce three-dimensional images (element 715 of FIG. 7 ) based on two captured images (elements 758A-B of FIG. 7 ) from the visible light cameras 114A-B, respectively, having the same timestamp. Such three-dimensional images 715 allow for an immersive life-like experience, e.g., for virtual reality or video gaming. For stereoscopic vision, the pair of images 758A-B are generated at a given moment in time—one image for each of the left and right visible light cameras 114A-B. When the pair of generated images 758A-B from the frontward facing angles of coverage 111A-B of the left and right visible light cameras 114A-B are stitched together (e.g., by the image processor 912), depth perception is provided by the optical assembly 180A-B.

In an example, a user interface field of view adjustment system includes the eyewear device 100. The eyewear device 100 includes a frame 105, a right temple 110B extending from a right lateral side 170B of the frame 105, and a see-through image display 180D (FIGS. 2A-B) comprising optical assembly 180B to present a graphical user interface to a user. The eyewear device 100 includes the left visible light camera 114A connected to the frame 105 or the left temple 110A to capture a first image of the scene. Eyewear device 100 further includes the right visible light camera 114B connected to the frame 105 or the right temple 110B to capture (e.g., simultaneously with the left visible light camera 114A) a second image of the scene which partially overlaps the first image. Although not shown in FIGS. 1A-B, the user interface field of view adjustment system further includes the processor 932 coupled to the eyewear device 100 and connected to the visible light cameras 114A-B, the memory 934 accessible to the processor 932, and programming in the memory 934, for example in the eyewear device 100 itself or another part of the user interface field of view adjustment system.

Although not shown in FIG. 1A, the eyewear device 100 also includes a head movement tracker (element 109 of FIG. 1B) or an eye movement tracker (element 213 of FIGS. 2A-B). Eyewear device 100 further includes the see-through image displays 180C-D of optical assembly 180A-B for presenting a sequence of displayed images, and an image display driver (element 942 of FIG. 9 ) coupled to the see-through image displays 180C-D of optical assembly 180A-B to control the image displays 180C-D of optical assembly 180A-B to present the sequence of displayed images 715, which are described in further detail below. Eyewear device 100 further includes the memory 934 and the processor 932 having access to the image display driver 942 and the memory 934. Eyewear device 100 further includes programming (element 934 of FIG. 9 ) in the memory. Execution of the programming by the processor 932 configures the eyewear device 100 to perform functions, including functions to present, via the see-through image displays 180C-D, an initial displayed image of the sequence of displayed images, the initial displayed image having an initial field of view corresponding to an initial head direction or an initial eye gaze direction (element 230 of FIG. 5 ).

Execution of the programming by the processor 932 further configures the eyewear device 100 to detect movement of a user of the eyewear device by: (i) tracking, via the head movement tracker (element 109 of FIG. 1B), a head movement of a head of the user, or (ii) tracking, via an eye movement tracker (element 213 of FIGS. 2A-B, FIG. 5 ), an eye movement of an eye of the user of the eyewear device 100. Execution of the programming by the processor 932 further configures the eyewear device 100 to determine a field of view adjustment to the initial field of view of the initial displayed image based on the detected movement of the user. The field of view adjustment includes a successive field of view corresponding to a successive head direction or a successive eye direction. Execution of the programming by the processor 932 further configures the eyewear device 100 to generate a successive displayed image of the sequence of displayed images based on the field of view adjustment. Execution of the programming by the processor 932 further configures the eyewear device 100 to present, via the see-through image displays 180C-D of the optical assembly 180A-B, the successive displayed images.

FIG. 1B is a top cross-sectional view of the temple of the eyewear device 100 of FIG. 1A depicting the right visible light camera 114B, a head movement tracker 109, and a circuit board. Construction and placement of the left visible light camera 114A is substantially similar to the right visible light camera 114B, except the connections and coupling are on the left lateral side 170A. As shown, the eyewear device 100 includes the right visible light camera 114B, a circuit board, which may be a flexible printed circuit board (PCB) 140, and a battery 142 configured to power eyewear 100. The left hinge 226A connects the left temple 110A to a left temple extension 125A of the eyewear device 100. In some examples, components of the left visible light camera 114A, the flexible PCB 140, or other electrical connectors or contacts may be located on the left temple extension 125A or the left hinge 226A. The right hinge 226B connects the right temple 110B to a right temple extension 125B of the eyewear device 100. In some examples, components of the right visible light camera 114B, the flexible PCB 140, or other electrical connectors or contacts may be located on the right temple extension 125B or the right hinge 226B.

As shown, eyewear device 100 has a head movement tracker 109, which includes, for example, an inertial measurement unit (IMU). An inertial measurement unit is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the magnetic field surrounding the body, using a combination of accelerometers and gyroscopes, sometimes also magnetometers. The inertial measurement unit works by detecting linear acceleration using one or more accelerometers and rotational rate using one or more gyroscopes. Typical configurations of inertial measurement units contain one accelerometer, gyro, and magnetometer per axis for each of the three axes: horizontal axis for left-right movement (X), vertical axis (Y) for top-bottom movement, and depth or distance axis for up-down movement (Z). The accelerometer detects the gravity vector. The magnetometer defines the rotation in the magnetic field (e.g., facing south, north, etc.) like a compass which generates a heading reference. The three accelerometers to detect acceleration along the horizontal, vertical, and depth axis defined above, which can be defined relative to the ground, the eyewear device 100, or the user wearing the eyewear device 100.

Eyewear device 100 detects movement of the user of the eyewear device 100 by tracking, via the head movement tracker 109, the head movement of the head of the user. The head movement includes a variation of head direction on a horizontal axis, a vertical axis, or a combination thereof from the initial head direction during presentation of the initial displayed image on the image display. In one example, tracking, via the head movement tracker 109, the head movement of the head of the user includes measuring, via the inertial measurement unit 109, the initial head direction on the horizontal axis (e.g., X axis), the vertical axis (e.g., Y axis), or the combination thereof (e.g., transverse or diagonal movement). Tracking, via the head movement tracker 109, the head movement of the head of the user further includes measuring, via the inertial measurement unit 109, a successive head direction on the horizontal axis, the vertical axis, or the combination thereof during presentation of the initial displayed image.

Tracking, via the head movement tracker 109, the head movement of the head of the user further includes determining the variation of head direction based on both the initial head direction and the successive head direction. Detecting movement of the user of the eyewear device 100 further includes in response to tracking, via the head movement tracker 109, the head movement of the head of the user, determining that the variation of head direction exceeds a deviation angle threshold on the horizontal axis, the vertical axis, or the combination thereof. The deviation angle threshold is between about 3° to 10°. As used herein, the term “about” when referring to an angle means ±10% from the stated amount.

Variation along the horizontal axis slides three-dimensional objects, such as characters, Bitmojis, application icons, etc. in and out of the field of view by, for example, hiding, unhiding, or otherwise adjusting visibility of the three-dimensional object. Variation along the vertical axis, for example, when the user looks upwards, in one example, displays weather information, time of day, date, calendar appointments, etc. In another example, when the user looks downwards on the vertical axis, the eyewear device 100 may power down.

The right temple 110B includes temple body 211 and a temple cap, with the temple cap omitted in the cross-section of FIG. 1B. Disposed inside the right temple 110B are various interconnected circuit boards, such as PCBs or flexible PCBs, that include controller circuits for right visible light camera 114B, microphone(s) 130, speaker(s) 132, low-power wireless circuitry and antennas (e.g., for wireless short-range network communication via Bluetooth™), and high-speed wireless circuitry and antennas (e.g., for wireless local area network communication via WiFi and positioning via GPS).

The right visible light camera 114B is coupled to or disposed on the flexible PCB 240 and covered by a visible light camera cover lens, which is aimed through opening(s) formed in the right temple 110B. In some examples, the frame 105 connected to the right temple 110B includes the opening(s) for the visible light camera cover lens. The frame 105 includes a front-facing side configured to face outwards away from the eye of the user. The opening for the visible light camera cover lens is formed on and through the front-facing side. In the example, the right visible light camera 114B has an outward facing angle of coverage 111B with a line of sight or perspective of the right eye of the user of the eyewear device 100. The visible light camera cover lens can also be adhered to an outward facing surface of the right temple 110B in which an opening is formed with an outwards facing angle of coverage, but in a different outwards direction. The coupling can also be indirect via intervening components.

Left (first) visible light camera 114A is connected to the left see-through image display 180C of left optical assembly 180A to generate a first background scene of a first successive displayed image. The right (second) visible light camera 114B is connected to the right see-through image display 180D of right optical assembly 180B to generate a second background scene of a second successive displayed image. The first background scene and the second background scene partially overlap to present a three-dimensional observable area of the successive displayed image.

Flexible PCB 140 is disposed inside the right temple 110B and is coupled to one or more other components housed in the right temple 110B. Although shown as being formed on the circuit boards of the right temple 110B, the right visible light camera 114B can be formed on the circuit boards of the left temple 110A, the temple extensions 125A-B, or frame 105.

FIG. 2A is a rear view of an example hardware configuration of an eyewear device 100, which includes an eye scanner 213 on a frame 105, for use in a system for determining an eye position and gaze direction of a wearer/user of the eyewear device 100. As shown in FIG. 2A, the eyewear device 100 is in a form configured for wearing by a user, which are eyeglasses in the example of FIG. 2A. The eyewear device 100 can take other forms and may incorporate other types of frameworks, for example, a headgear, a headset, or a helmet.

In the eyeglasses example, eyewear device 100 includes the frame 105 which includes the left rim 107A connected to the right rim 107B via the bridge 106 adapted for a nose of the user. The left and right rims 107A-B include respective apertures 175A-B which hold the respective optical element 180A-B, such as a lens and the see-through displays 180C-D. As used herein, the term lens is meant to cover transparent or translucent pieces of glass or plastic having curved and flat surfaces that cause light to converge/diverge or that cause little or no convergence/divergence.

Although shown as having two optical elements 180A-B, the eyewear device 100 can include other arrangements, such as a single optical element depending on the application or intended user of the eyewear device 100. As further shown, eyewear device 100 includes the left temple 110A adjacent the left lateral side 170A of the frame 105 and the right temple 110B adjacent the right lateral side 170B of the frame 105. The temples 110A-B may be integrated into the frame 105 on the respective sides 170A-B (as illustrated) or implemented as separate components attached to the frame 105 on the respective sides 170A-B. Alternatively, the temples 110A-B may be integrated into temples (not shown) attached to the frame 105.

In the example of FIG. 2A, the eye scanner 213 includes an infrared emitter 115 and an infrared camera 120. Visible light cameras typically include a blue light filter to block infrared light detection, in an example, the infrared camera 120 is a visible light camera, such as a low-resolution video graphic array (VGA) camera (e.g., 640×480 pixels for a total of 0.3 megapixels), with the blue filter removed. The infrared emitter 115 and the infrared camera 120 are co-located on the frame 105, for example, both are shown as connected to the upper portion of the left rim 107A. The frame 105 or one or more of the left and right temples 110A-B include a circuit board (not shown) that includes the infrared emitter 115 and the infrared camera 120. The infrared emitter 115 and the infrared camera 120 can be connected to the circuit board by soldering, for example.

Other arrangements of the infrared emitter 115 and infrared camera 120 can be implemented, including arrangements in which the infrared emitter 115 and infrared camera 120 are both on the right rim 107B, or in different locations on the frame 105, for example, the infrared emitter 115 is on the left rim 107A and the infrared camera 120 is on the right rim 107B. In another example, the infrared emitter 115 is on the frame 105 and the infrared camera 120 is on one of the temples 110A-B, or vice versa. The infrared emitter 115 can be connected essentially anywhere on the frame 105, left temple 110A, or right temple 110B to emit a pattern of infrared light. Similarly, the infrared camera 120 can be connected essentially anywhere on the frame 105, left temple 110A, or right temple 110B to capture at least one reflection variation in the emitted pattern of infrared light.

The infrared emitter 115 and infrared camera 120 are arranged to face inwards towards an eye of the user with a partial or full field of view of the eye in order to identify the respective eye position and gaze direction. For example, the infrared emitter 115 and infrared camera 120 are positioned directly in front of the eye, in the upper part of the frame 105 or in the temples 110A-B at either ends of the frame 105.

FIG. 2B is a rear view of an example hardware configuration of another eyewear device 200. In this example configuration, the eyewear device 200 is depicted as including an eye scanner 213 on a right temple 210B. As shown, an infrared emitter 215 and an infrared camera 220 are co-located on the right temple 210B. It should be understood that the eye scanner 213 or one or more components of the eye scanner 213 can be located on the left temple 210A and other locations of the eyewear device 200, for example, the frame 105. The infrared emitter 215 and infrared camera 220 are like that of FIG. 2A, but the eye scanner 213 can be varied to be sensitive to different light wavelengths as described previously in FIG. 2A.

Similar to FIG. 2A, the eyewear device 200 includes a frame 105 which includes a left rim 107A which is connected to a right rim 107B via a bridge 106; and the left and right rims 107A-B include respective apertures which hold the respective optical elements 180A-B comprising the see-through display 180C-D.

FIGS. 2C-D are rear views of example hardware configurations of the eyewear device 100, including two different types of see-through image displays 180C-D. In one example, these see-through image displays 180C-D of optical assembly 180A-B include an integrated image display. As shown in FIG. 2C, the optical assemblies 180A-B includes a suitable display matrix 180C-D of any suitable type, such as a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, a waveguide display, or any other such display. The optical assembly 180A-B also includes an optical layer or layers 176, which can include lenses, optical coatings, prisms, mirrors, waveguides, optical strips, and other optical components in any combination. The optical layers 176A-N can include a prism having a suitable size and configuration and including a first surface for receiving light from display matrix and a second surface for emitting light to the eye of the user. The prism of the optical layers 176A-N extends over all or at least a portion of the respective apertures 175A-B formed in the left and right rims 107A-B to permit the user to see the second surface of the prism when the eye of the user is viewing through the corresponding left and right rims 107A-B. The first surface of the prism of the optical layers 176A-N faces upwardly from the frame 105 and the display matrix overlies the prism so that photons and light emitted by the display matrix impinge the first surface. The prism is sized and shaped so that the light is refracted within the prism and is directed towards the eye of the user by the second surface of the prism of the optical layers 176A-N. In this regard, the second surface of the prism of the optical layers 176A-N can be convex to direct the light towards the center of the eye. The prism can optionally be sized and shaped to magnify the image projected by the see-through image displays 180C-D, and the light travels through the prism so that the image viewed from the second surface is larger in one or more dimensions than the image emitted from the see-through image displays 180C-D.

In another example, the see-through image displays 180C-D of optical assembly 180A-B include a projection image display as shown in FIG. 2D. The optical assembly 180A-B includes a laser projector 150, which is a three-color laser projector using a scanning mirror or galvanometer. During operation, an optical source such as a laser projector 150 is disposed in or on one of the temple extensions 125A-B of the eyewear device 100. Optical assembly 180A-B includes one or more optical strips 155A-N spaced apart across the width of the lens of the optical assembly 180A-B or across a depth of the lens between the front surface and the rear surface of the lens.

As the photons projected by the laser projector 150 travel across the lens of the optical assembly 180A-B, the photons encounter the optical strips 155A-N. When a particular photon encounters a particular optical strip, the photon is either redirected towards the user's eye, or it passes to the next optical strip. A combination of modulation of laser projector 150, and modulation of optical strips, may control specific photons or beams of light. In an example, a processor controls optical strips 155A-N by initiating mechanical, acoustic, or electromagnetic signals. Although shown as having two optical assemblies 180A-B, the eyewear device 100 can include other arrangements, such as a single or three optical assemblies, or the optical assembly 180A-B may have arranged different arrangement depending on the application or intended user of the eyewear device 100.

As further shown in FIGS. 2C-D, eyewear device 100 includes a left temple 110A adjacent the left lateral side 170A of the frame 105 and a right temple 110B adjacent the right lateral side 170B of the frame 105. The temples 110A-B may be integrated into the frame 105 on the respective lateral sides 170A-B (as illustrated) or implemented as separate components attached to the frame 105 on the respective sides 170A-B. Alternatively, the temples 110A-B may be integrated into temple extensions 125A-B attached to the frame 105.

In one example, the see-through image displays include the first see-through image display 180C and the second see-through image display 180D. Eyewear device 100 includes first and second apertures 175A-B which hold the respective first and second optical assembly 180A-B. The first optical assembly 180A includes the first see-through image display 180C (e.g., a display matrix of FIG. 2C or optical strips 155A-N′ and a projector 150A). The second optical assembly 180B includes the second see-through image display 180D e.g., a display matrix of FIG. 2C or optical strips 155A-N″ and a projector 150B). The successive field of view of the successive displayed image includes an angle of view between about 15° to 30, and more specifically 24°, measured horizontally, vertically, or diagonally. The successive displayed image having the successive field of view represents a combined three-dimensional observable area visible through stitching together of two displayed images presented on the first and second image displays.

As used herein, “an angle of view” describes the angular extent of the field of view associated with the displayed images presented on each of the left and right image displays 180C-D of optical assembly 180A-B. The “angle of coverage” describes the angle range that a lens of visible light cameras 114A-B or infrared camera 220 can image. Typically, the image circle produced by a lens is large enough to cover the film or sensor completely, possibly including some vignetting (i.e., a reduction of an image's brightness or saturation toward the periphery compared to the image center). If the angle of coverage of the lens does not fill the sensor, the image circle will be visible, typically with strong vignetting toward the edge, and the effective angle of view will be limited to the angle of coverage. The “field of view” is intended to describe the field of observable area which the user of the eyewear device 100 can see through his or her eyes via the displayed images presented on the left and right image displays 180C-D of the optical assembly 180A-B. Image display 180C of optical assembly 180A-B can have a field of view with an angle of coverage between 15° to 30°, for example 24°, and have a resolution of 480×480 pixels.

FIG. 3 shows a rear perspective view of the eyewear device of FIG. 2A. The eyewear device 100 includes an infrared emitter 215, infrared camera 220, a frame front 330, a frame back 335, and a circuit board 340. It can be seen in FIG. 3 that the upper portion of the left rim of the frame of the eyewear device 100 includes the frame front 330 and the frame back 335. An opening for the infrared emitter 215 is formed on the frame back 335.

As shown in the encircled cross-section 4 in the upper middle portion of the left rim of the frame, a circuit board, which is a flexible PCB 340, is sandwiched between the frame front 330 and the frame back 335. Also shown in further detail is the attachment of the left temple 110A to the left temple 325A via the left hinge 326A. In some examples, components of the eye movement tracker 213, including the infrared emitter 215, the flexible PCB 340, or other electrical connectors or contacts may be located on the left temple 325A or the left hinge 326A.

FIG. 4 is a cross-sectional view through the infrared emitter 215 and the frame corresponding to the encircled cross-section 4 of the eyewear device of FIG. 3 . Multiple layers of the eyewear device 100 are illustrated in the cross-section of FIG. 4 , as shown the frame includes the frame front 330 and the frame back 335. The flexible PCB 340 is disposed on the frame front 330 and connected to the frame back 335. The infrared emitter 215 is disposed on the flexible PCB 340 and covered by an infrared emitter cover lens 445. For example, the infrared emitter 215 is reflowed to the back of the flexible PCB 340. Reflowing attaches the infrared emitter 215 to contact pad(s) formed on the back of the flexible PCB 340 by subjecting the flexible PCB 340 to controlled heat which melts a solder paste to connect the two components. In one example, reflowing is used to surface mount the infrared emitter 215 on the flexible PCB 340 and electrically connect the two components. However, it should be understood that through-holes can be used to connect leads from the infrared emitter 215 to the flexible PCB 340 via interconnects, for example.

The frame back 335 includes an infrared emitter opening 450 for the infrared emitter cover lens 445. The infrared emitter opening 450 is formed on a rear-facing side of the frame back 335 that is configured to face inwards towards the eye of the user. In the example, the flexible PCB 340 can be connected to the frame front 330 via the flexible PCB adhesive 460. The infrared emitter cover lens 445 can be connected to the frame back 335 via infrared emitter cover lens adhesive 455. The coupling can also be indirect via intervening components.

In an example, the processor 932 utilizes eye tracker 213 to determine an eye gaze direction 230 of a wearer's eye 234 as shown in FIG. 5 , and an eye position 236 of the wearer's eye 234 within an eyebox as shown in FIG. 6 . The eye tracker 213 is a scanner which uses infrared light illumination (e.g., near-infrared, short-wavelength infrared, mid-wavelength infrared, long-wavelength infrared, or far infrared) to captured image of reflection variations of infrared light from the eye 234 to determine the gaze direction 230 of a pupil 232 of the eye 234, and also the eye position 236 with respect to the see-through display 180D.

FIG. 7 depicts an example of capturing visible light with cameras. Visible light is captured by the left visible light camera 114A with a left visible light camera field of view 111A as a left raw image 758A. Visible light is captured by the right visible light camera 114B with a right visible light camera field of view 111B as a right raw image 758B. Based on processing of the left raw image 758A and the right raw image 758B, a three-dimensional depth map 715 of a three-dimensional scene, referred to hereafter as an image, is generated by processor 932.

Commercial UAVs typically include a camera for imaging the earth and other objects below, for instance, capturing still images and film. In some versions, the camera is fixed to the UAV, without the use of a gimbal for selectively positioning the camera. More complicated UAVs include an electronic receiver and an electronically configurable gimble and camera. A remotely located controller in eyewear 100 establishes a wireless control link with the receiver of the UAV to control the UAV, as well as the gimble and camera.

Referring to FIG. 8A, there is shown a side view of an example hardware configuration of the eyewear device 100, which includes a touchpad 182 located on the temple 110B of the frame 105. The touchpad 182 may also be located on temple 110A, or another portion of the frame 105. The touchpad 182 is configured to receive user input from the user. For example, the user input sensed by the touchpad 182 may be a swipe, tap, or hold of the touchpad 182 with the user's finger. The touchpad 182 may be configured and customized to recognize other user interactions with the touchpad 182 to be an input signal for the control of a variety of functions done by the eyewear 100. These functions may consist of, but not limited to, selecting or moving between menu options, turning on or off the eyewear 100, capturing an image, pausing or playing music, answering or ending a phone call, and controlling a wireless connected device.

Referring now to FIG. 8B, one example of the eyewear 100 controlling the UAV 800 is shown. The eyewear 100 is coupled to the UAV 800 via a wireless connection 802 to send control signals from the eyewear 100 to the UAV 800 as a function of eyewear user input. The control signals may determine or alter the UAV's 800 flight path. For example, a control signal instructing the UAV 800 to move vertically, laterally, or to proceed towards a predetermined waypoint may be sent by the eyewear 100 as a function of the user input. Additionally, a signal from the UAV 800 may be sent to the eyewear 100 to transmit a varying amount of information including, but not limited to, the UAV's 800 heading, location, speed, and video feed or image from the camera 820 located on the UAV 800. This information may be displayed on the image display 180C-D of the eyewear 100.

FIG. 8C illustrates a perspective view of a UAV 800 having a body 812 and a plurality of propellers 814 including multiple blades 816. The propeller 814 including blades 816 can be made out of metal or non-conductive material. Typically, non-conductive materials, such as plastic, are used since they are lighter.

Also shown in FIG. 8C is a camera 820 fixed to the body 812 at one side thereof shown at 818 at a fixed pitch angle with respect to the body 812. In this example, the camera 820 is facing horizontal from the body 812 so that the camera pitch angle is zero degrees. In other examples, the camera pitch angle can also be fixed at other pitch angles, such as −5 degrees downward from horizontal, or other pitch angles as desired.

FIG. 8D illustrates a UAV control system 850 configured to control the UAV 800 as a function of the received control signals from the eyewear 100, including UAV operation along a flight path (FP). The control system 850 includes an electronic processor 852 comprising a flight controller, a memory 854 including flight plans, instructions and code for operating processor 852 to control and operate the UAV 800, data tables 856 stored in memory 854, a global positioning system (GPS) receiver 858 for providing global positioning of the UAV 800, an RF transceiver 870, and a 3-axis magnetometer 872. The electronic processor 852 establishes the FP of the UAV 800 based on performance data in data tables 856 and the GPS 858, and the received control signals from eyewear 100. Multiple flight paths are stored in memory 854, wherein the flight paths can be custom programmed and downloaded by into memory 854 by a user of the UAV 800 wirelessly using wireless connection 802 or by a cable.

FIG. 8E illustrates a graphical representation of a flight path FP1 that routes the UAV 800 from a starting position 860 to an end position 862. The FP1 routes the UAV 800 along a smooth path at varying altitudes to a target(s) 864, also referred to as a point of interest (POI). The target 864 can comprise of many features including buildings, trees, people etc. The limited or restricted spacing around the target 864 constrains and may limit the maneuvering of the UAV 800 about target 864, and thus the camera imaging. This spacing creates difficulty for the UAV 800 having a fixed position camera 820.

FIG. 8F illustrates a graphical representation of a more complex flight path FP2 that the UAV 800 traverses to and about target 864. The flight path FP2 includes multiple waypoints WP and multiple image capture points including image capture points CP1 and CP2. The flight path FP2 also includes performance variables of the UAV 800, and the orientation of the UAV 800 including a pitch angle PA of the camera 820 with respect to horizontal at each waypoint, including proximate the image capture points CP1 and CP2. In this example, the UAV 800 traverses the flight path FP2 having multiple waypoints to image capture point CP1 proximate the target 864.

In an example, the flight path FP2 orients the UAV 800 such that the camera 820 (and the side of body 812) is directed upwardly at a pitch angle PA3 facing target 864 when approaching, and at, image capture point CP1. The camera 820 captures images of target 864 at image capture point CP1 for a predetermine image capture time and stores the images in memory 854. The UAV 800 subsequently traverses flight path FP2 to image capture point CP2 proximate target 864. The flight path FP2 also orients the UAV 800 such that the camera 820 (and the side of body 812) is directed downwardly at a pitch angle PA5 toward target 864. The camera 820 again captures images at image capture point CP2 and stores the images in memory 854.

Since the camera 820 is fixed to body 812 at the fixed pitch angle, orienting the UAV 800 in a predetermined stable position at an angle is not an ordinary task. More importantly, establishing a predetermined camera angle of the camera 820 relative to the target 864 at capture points CP1 and CP2, is not an ordinary task. The flight paths are automatically determined by electronic processor 852 based upon the GPS position of the capture points CP1 and CP2, and the desired camera pitch angle at capture points CP1 and CP2. The processor 852 determines the operational parameters of the UAV 800, and it takes into account the weight and flight performance of the UAV 800. The determined flight paths increase the image capture time at capture points CP1 and CP2, at the desired pitch angle, which is very beneficial for imaging.

The UAV 800 includes the 3-axis magnetometer 872 so that the processor 852 can measure a change in angle as the UAV 800 drone flies North/South. (The 3-axis magnetometer 872 does not detect East/West movement). The processor 852 compares the heading data of the 3-axis magnetometer 872 to the heading data from the GPS 858, and determines if this heading information is correlated. An alert to the ground station is generated by the UAV 800 if there is a data mismatch. The ground station can respond, such as by instructing the UAV 800 to return to the ground station. In addition, the UAV 800 may unilaterally decide to return to the home station, such as if it is on an unprogrammed path.

Referring back to FIG. 8B, there are multiple examples for the eyewear 100 to control the UAV 800. A variety of inputs may be used by the user of the eyewear 100 to generate the control signals for the UAV 800. One example of an input used by the user includes the touchpad 182 of the eyewear 100 configured to generate input signals to the processor 932 (FIG. 9 ). The processor 932 of the eyewear 100 is responsive to the received input signals generated by the touchpad 182 and generates control signals that are sent to the UAV 800 via the wireless connection 802. For example, a swipe up by the user's finger on the touchpad 182 may result in a control signal for the UAV 800 to gain altitude, a swipe down may result in the decrease in altitude or landing, a swipe forward may result in the UAV 800 moving forward or to gain forward velocity, a swipe backwards may result in the UAV slowing down, stopping, or moving backwards.

Another example of an input being used to control the UAV 800 includes the head movement tracker 109 of the eyewear 100 configured to control the UAV 800 by measuring the movements of the user's head. The processor 932 of the eyewear 100 is responsive to the input signal generated by the head movement tracker 109 and generates control signals that are sent to the UAV 800 via the wireless connection 802. For example, a user turning their head to the left may be measured by the head movement tracker 109 and result in a control signal for the UAV 800 to turn left. Additionally, the user looking upwards may result in a control signal for the UAV 800 to gain altitude. Specific head gestures, movements, or combinations of head movements are recognized by the processor 932, which in turn generates custom control signals for controlling the UAV. For example, the user shaking their head back and forth is detected by the head movement tracker 109 and results in a control signal sent to the UAV 800 to cancel the current flight path and return to the user.

Another example of an input being used to control the UAV includes the microphone 130 of the eyewear 100 configured to control the UAV 800 by voice commands of the user. The processor 932 of the eyewear 100 is responsive to the input signal generated by the microphone 130 to send control signals to the UAV 800 via a wireless connection 802. For example, the user may generate the voice command, “UAV go up,” to result in the eyewear 100 sending a control signal to the UAV 800 resulting in the UAV 800 gaining a predetermine altitude, such as 10 ft. A subsequent voice command of “Up” would cause the UAV to go up another predetermined amount, such as 10 ft. Voice commands may be used alter the flight path of the UAV 800 by changing the heading, speed, and altitude of the UAV 800. Voice commands may also be used to cancel the current flight path or land the UAV 800.

In another example, the input can be one of the cameras 114. The camera 114 may be configured to detect mid-air gestures of the user to control the UAV 800. For example, the user can motion a finger or hand forward of the eyewear to result in the eyewear 100 sending a control signal to the UAV 800, resulting in the UAV going forward. If the user raises a finger or hand upwardly, then the UAV 800 would responsively gain altitude.

Referring to FIG. 9 , the figure depicts a high-level functional block diagram including example electronic components disposed in eyewear 100/200. The illustrated electronic components include the processor 932, the memory 934, and the see-through image display 180C and 180D including the embedded antennas 808.

Memory 934 includes instructions for execution by processor 932 to implement functionality of eyewear 100/200, including instructions for processor 932 to control in the image 715. Processor 932 receives power from battery (not shown) and executes the instructions stored in memory 934, or integrated with the processor 932 on-chip, to perform functionality of eyewear 100/200, and communicating with external devices via wireless connections.

A user interface adjustment system 900 includes a wearable device, which is the eyewear device 100 with an eye movement tracker 213 (e.g., shown as infrared emitter 215 and infrared camera 220 in FIG. 2B). User interface adjustments system 900 also includes a mobile device 990 and a server system 998 connected via various networks. Mobile device 990 may be a smartphone, tablet, laptop computer, access point, or any other such device capable of connecting with eyewear device 100 using both a low-power wireless connection 925 and a high-speed wireless connection 937. Mobile device 990 is connected to server system 998 and network 995. The network 995 may include any combination of wired and wireless connections.

The eyewear device 100 includes multiple inputs including the microphone 130, the touchpad 182, the head movement tracker 109 and camera 114 each configured to create input signals for the processor 932. The processor 932 responsively generates control signals that are communicated with the UAV 800 using either, or both, a low-power wireless connection 950 and a high-speed wireless connection 952, which collectively are referred to as the wireless connection 802. UAV 800 may be a drone, helicopter, plane, or any other such device capable of moving through the air without a pilot onboard.

Eyewear device 100 includes at least two visible light cameras 114A-B (one associated with the left lateral side 170A and one associated with the right lateral side 170B). Eyewear device 100 further includes two see-through image displays 180C-D of the optical assembly 180A-B (one associated with the left lateral side 170A and one associated with the right lateral side 170B). Eyewear device 100 also includes image display driver 942, image processor 912, low-power circuitry 920, and high-speed circuitry 930. The components shown in FIG. 9 for the eyewear device 100/200 are located on one or more circuit boards, for example a PCB or flexible PCB, in the temples 110A-B as previously described. Alternatively, or additionally, the depicted components can be located in the temples, frames, hinges, or bridge of the eyewear device 100. Left and right visible light cameras 114A-B can include digital camera elements such as a complementary metal-oxide-semiconductor (CMOS) image sensor, charge coupled device, a lens, or any other respective visible or light capturing elements that may be used to capture data, including images of scenes with unknown objects.

Eye movement tracking programming 945 implements the user interface field of view adjustment instructions, including, to cause the eyewear device 100 to track, via the eye movement tracker 213, the eye movement of the eye of the user of the eyewear device 100. Other implemented instructions (functions) cause the eyewear device 100 to determine, a field of view adjustment to the initial field of view of an initial displayed image based on the detected eye movement of the user corresponding to a successive eye direction. Further implemented instructions generate a successive displayed image of the sequence of displayed images based on the field of view adjustment. The successive displayed image is produced as visible output to the user via the user interface. This visible output appears on the see-through image displays 180C-D of optical assembly 180A-B, which is driven by image display driver 934 to present the sequence of displayed images, including the initial displayed image with the initial field of view and the successive displayed image with the successive field of view.

As shown in FIG. 9 , high-speed circuitry 930 includes high-speed processor 932, memory 934, and high-speed wireless circuitry 936. In the example, the image display driver 942 is coupled to the high-speed circuitry 930 and operated by the high-speed processor 932 in order to drive the left and right image displays 180C-D of the optical assembly 180A-B to create the virtual image. High-speed processor 932 may be any processor capable of managing high-speed communications and operation of any general computing system needed for eyewear device 100. High-speed processor 932 includes processing resources needed for managing high-speed data transfers on high-speed wireless connection 937 to a wireless local area network (WLAN) using high-speed wireless circuitry 936. In certain examples, the high-speed processor 932 executes an operating system such as a LINUX operating system or other such operating system of the eyewear device 100 and the operating system is stored in memory 934 for execution. In addition to any other responsibilities, the high-speed processor 932 executing a software architecture for the eyewear device 100 is used to manage data transfers with high-speed wireless circuitry 936. In certain examples, high-speed wireless circuitry 936 is configured to implement Institute of Electrical and Electronic Engineers (IEEE) 802.11 communication standards, also referred to herein as Wi-Fi. In other examples, other high-speed communications standards may be implemented by high-speed wireless circuitry 936.

Low-power wireless circuitry 924 and the high-speed wireless circuitry 936 of the eyewear device 100 can include short range transceivers (e.g., UWB or Bluetooth™) and wireless wide, local, or wide area network transceivers (e.g., cellular or WiFi) including antennas 808. Mobile device 990, including the transceivers communicating via the low-power wireless connection 925 and high-speed wireless connection 937, may be implemented using details of the architecture of the eyewear device 100, as can other elements of network 995.

Memory 934 includes any storage device capable of storing various data and applications, including, among other things, color maps, camera data generated by the left and right visible light cameras 114A-B and the image processor 912, as well as images generated for display by the image display driver 942 on the see-through image displays 180C-D of the optical assembly 180A-B. While memory 934 is shown as integrated with high-speed circuitry 930, in other examples, memory 934 may be an independent standalone element of the eyewear device 100. In certain such examples, electrical routing lines may provide a connection through a chip that includes the high-speed processor 932 from the image processor 912 or low-power processor 922 to the memory 934. In other examples, the high-speed processor 932 may manage addressing of memory 934 such that the low-power processor 922 will boot the high-speed processor 932 any time that a read or write operation involving memory 934 is needed.

Server system 998 may be one or more computing devices as part of a service or network computing system, for example, that include a processor, a memory, and network communication interface to communicate over the network 995 with the mobile device 990 and eyewear device 100. Eyewear device 100 is connected with a host computer. For example, the eyewear device 100 is paired with the mobile device 990 via the high-speed wireless connection 937 or connected to the server system 998 via the network 995.

Output components of the eyewear device 100 include visual components, such as the left and right image displays 180C-D of optical assembly 180A-B as described in FIGS. 2C-D (e.g., a display such as a liquid crystal display (LCD), a plasma display panel (PDP), a light emitting diode (LED) display, a projector, or a waveguide). The image displays 180C-D of the optical assembly 180A-B are driven by the image display driver 942. The output components of the eyewear device 100 further include acoustic components (e.g., speakers), haptic components (e.g., a vibratory motor), other signal generators, and so forth. The input components of the eyewear device 100, the mobile device 990, and server system 998, may include alphanumeric input components (e.g., a keyboard, a touch screen configured to receive alphanumeric input, a photo-optical keyboard, or other alphanumeric input components), point-based input components (e.g., a mouse, a touchpad, a trackball, a joystick, a motion sensor, or other pointing instruments), tactile input components (e.g., a physical button, a touch screen that provides location and force of touches or touch gestures, or other tactile input components), audio input components (e.g., a microphone), and the like.

Eyewear device 100 may optionally include additional peripheral device elements 919. Such peripheral device elements may include biometric sensors, additional sensors, or display elements integrated with eyewear device 100. For example, peripheral device elements 919 may include any I/O components including output components, motion components, position components, or any other such elements described herein. The eyewear device 100 can take other forms and may incorporate other types of frameworks, for example, a headgear, a headset, or a helmet.

For example, the biometric components of the user interface field of view adjustment 900 include components to detect expressions (e.g., hand expressions, facial expressions, vocal expressions, body gestures, or eye tracking), measure biosignals (e.g., blood pressure, heart rate, body temperature, perspiration, or brain waves), identify a person (e.g., voice identification, retinal identification, facial identification, fingerprint identification, or electroencephalogram based identification), and the like. The motion components include acceleration sensor components (e.g., accelerometer), gravitation sensor components, rotation sensor components (e.g., gyroscope), and so forth. The position components include location sensor components to generate location coordinates (e.g., a Global Positioning System (GPS) receiver component), WiFi or Bluetooth™ transceivers to generate positioning system coordinates, altitude sensor components (e.g., altimeters or barometers that detect air pressure from which altitude may be derived), orientation sensor components (e.g., magnetometers), and the like. Such positioning system coordinates can also be received over wireless connections 925 and 937 from the mobile device 990 via the low-power wireless circuitry 924 or high-speed wireless circuitry 936.

According to some examples, an “application” or “applications” are program(s) that execute functions defined in the programs. Various programming languages can be employed to create one or more of the applications, structured in a variety of manners, such as object-oriented programming languages (e.g., Objective-C, Java, or C++) or procedural programming languages (e.g., C or assembly language). In a specific example, a third party application (e.g., an application developed using the ANDROID™ or IOS™ software development kit (SDK) by an entity other than the vendor of the particular platform) may be mobile software running on a mobile operating system such as IOS™, ANDROID™, WINDOWS® Phone, or another mobile operating systems. In this example, the third-party application can invoke API calls provided by the operating system to facilitate functionality described herein.

FIG. 10 is a flowchart 1000 illustrating the operation of the eyewear 100 controlling the UAV 800 based on the input of the user. These blocks do not need to be performed sequentially, and the processing and wireless communications can be performed simultaneously.

At block 1002, the user generates an input signal to the eyewear 100 using an input of the eyewear. This input can be the touchpad 182, the microphone 130, the head movement tracker 109, the camera 114, or another input sensor. The user touches the touchpad 182 with their fingers to generate input signals, speaks to generate a voice command, gestures their head to generate input signals, or gestures their hand in view of the camera. Other inputs may be used, and limitation to these inputs is not to be inferred.

At block 1004, the processor 932 translates the input signal to a control signal to be sent to the UAV 800. For example, if the user uses the voice command “UAV go faster,” the processor 932 responsively generates a control signal to increase the speed of the UAV 800 a predetermined amount, such as by 2 mph. If the user swipes the touchpad up, the processor 932 will generate a control signal to increase the altitude a predetermined amount, such as 10 ft. If the user creates a head gesture, such as a nod upwardly, the processor 932 will generate a control signal to increase the altitude a predetermined amount, such as 10 ft. If the user creates a hand gesture in view of the camera 114, such as moving the hand up, the processor 932 will generate a control signal to increase the altitude a predetermined amount, such as 10 ft.

At block 1006, the eyewear 100 transmits the control signal to the UAV 800. This transmission is communicated by wireless connection 802, which as detailed in FIG. 9 , may be via low-power wireless connection 950 and high-speed wireless connection 952. The eyewear 100 may also communicate with the UAV 800 by means of relaying the control signal through the mobile device 990.

At block 1008, the UAV 800 receives the transmitted control signal via transceiver 870 and the UAV processor 852 responsively generates the corresponding signals to the subunits of the UAV 800 for the execution of the control signal. For example, a control signal indicative of increasing the UAV 800 speed by 2 mph is received by the UAV 800 and a second control signal is then sent from the processor 852 to the propellers 814 to increase the UAV 800 speed by 2 mph. Additionally, the control signals received by the UAV 800 may alter the flight path of the UAV 800 or control the camera 820 to capture a still image or a video.
